We have developed a photoemission DC gun equipped with an alkali photocathode at QST for high current operation. The CsSb photocathode fabricated in our preparation system showed quantum efficiency of 5.8 %. We have generated 4 mA beam from the CsSb photocathode at 150 kV. The status of development will be presented.
